Common virus linked to increased MS risk in Americans

A new study suggests that a common virus could be linked to multiple sclerosis.

Common virus may elevate multiple sclerosis risk for many Americans

Researchers at the University of Illinois Chicago have uncovered a potential connection between the herpes simplex virus-1 and multiple sclerosis, a debilitating disease affecting one million Americans. Their findings indicate that the virus, commonly spread through kissing, may exacerbate the risk of developing MS. By gene-editing mice to lack a protective protein, the study observed that the virus led to significant nerve damage similar to what is seen in MS patients. The study highlights the challenges posed by HSV-1 reactivation, particularly in individuals with weakened immune systems. Currently, oral herpes affects about 124 million Americans, according to the CDC, suggesting a widespread health concern.

This research serves as a critical reminder of how common infections can have far-reaching implications. With nearly half of American adults affected by oral herpes, understanding its role in conditions like multiple sclerosis could pave the way for enhanced therapeutic approaches. The findings that HSV-1 may degrade the myelin sheath adds to the growing body of evidence linking viral infections with autoimmune responses. Health professionals need to consider such connections when treating the millions affected by MS and related conditions, potentially leading to new preventative strategies.

Highlights

As research progresses, these discoveries could lead to groundbreaking treatments for multiple sclerosis.
